979-7622 - A small pod of 6 to 8 Type B killer whales (Orcinus nanus) in dense first year sea ice south of the Antarctic Circle near Adelaide Island at 67Ã¸ 05.7?S 67Ã¸ 42.8?W in the Gullet, Antarctica, Southern Ocean. MORE INFO These animals are also often called killer whales, but this is a misnomer as this is actually the largest member of the dolphin family. The Type B killer whale is a proposed new species called Orcinus nanus, though this is not universally accepted in the scientific community yet. Type B killer whales specialize in hunting pinnipeds, although they have been documented taking penguins. The Antarctic population estimate is 70,000?80,000 for all types of killer whales.

979-7069 - Views of Adelaide Island. Adelaide Island (or Isla Adelaida or Isla Belgrano) is a large, mainly ice-covered island, 75 miles long and 20 miles wide, lying at the north side of Marguerite Bay off the west coast of the Antarctic Peninsula. The island lies within the Argentine, British and Chilean Antarctic claims, at 67Ã¸15&#39;S 68Ã¸30&#39;W 67.25Ã¸S 68.5Ã¸W/ -67.25; -68.5.Adelaide Island was discovered in 1832 by a British expedition under John Biscoe. The island was first surveyed by the French Antarctic Expedition (1908-1910) under Jean-Baptiste Charcot. The source of the island&#39;s name is unknown. British Antarctic Survey records state that Charcot named the island &#34;Adelie Land&#34; after the huge number of Adelie Penguins that lived on its coast (the penguins being named after the wife of Dumont d&#39;Urville). This in turn was turned into Adelaide Island by the British Graham Land Expedition (1934 -37). It has also been supposed that the island was in fact named by Biscoe himself for Queen Adelaide of the United Kingdom. The Island has 2 bases on it. The old Adelaide Island base (also known as Base T) was set up by the Falkland Islands Dependent Survey (FIDS), which became the British Antarctic Survey. The Base was closed due to an unstable skiway and operations were moved to the new Rothera Station during 1976 / 1977, this base remains open to this day. The old BAS base was transferred to the Chilean Authorities in 1984, when it was renamed Teniente Luis Carvajal Villaroel Antarctic Base. The station was then used as a summer only station by the Chileans. However the skiway, and &#39;ramp&#39; to the station from the plateau have all become so unstable, that the Chilean Air Force (FACh) have stopped all there activities there. The Chilean Navy have visited the station almost every summer to ensure it is in good keeping. BAS employees also visit the station during the winter when access from the plateau is easier.Due to the length of time that it has been inhabited the island is well
